[PATCH v4 04/10] configure: add --disable-colo-proxy option
Add option to not build filter-mirror, filter-rewriter and colo-compare when they are not needed. There could be more agile configuration, for example add separate options for each filter, but that may be done in future on demand. The aim of this patch is to make possible to disable the whole COLO Proxy subsystem.
